Boros Dwarves is a low-curve equipment-aggro deck, so Seam Rip cleanly exiles cheap threats like Dwarven Mauler or equipment like Lavaspur Boots (both mana value 2 or less) before they snowball. Interdimensional Web Watch is too slow to matter against this fast clock, so it comes out for Seam Rip and Rest in Peace, the latter cutting off any incidental graveyard recursion the opponent might bring in from their own sideboard. Michelangelo's Technique is also too slow here. Keep Great Divide Guide and Doc Aurlock as they help stabilize mana and rebuild after early pressure.
